Complete wireless system

The Gemini GMU100 is a UHF wireless microphone system that includes a dynamic handheld microphone and a matching receiver. It is designed for performers, presenters and content creators who need cable-free audio for karaoke, busking, weddings, conferences, streaming or podcasting. The plug-and-play design lets you connect and start within seconds.

Sustained operation

Both the microphone and receiver run on built-in rechargeable lithium batteries, with the microphone using a user-replaceable 18650 1200mAh cell. A full charge delivers hours of continuous use, so the system stays live through long sets or events without needing a mains connection. Battery status and channel information are shown on the microphone's LED display.

UHF range limits

The system operates on UHF frequencies with a quoted wireless range over 50 meters, giving freedom of movement across stages or venues. Signal stability holds up to that distance, but physical obstacles, competing RF sources or crowded spectrum environments can reduce the practical working range. The expandable architecture allows additional compatible units to be added when more channels are required.

Questions about this item

How much heat or noise does the receiver add when it runs all day on its internal battery?

The receiver uses a built-in rechargeable lithium cell and has no moving parts, so it adds no audible fan noise and only negligible warmth during continuous operation.

What audio input must my mixer or speaker provide for the receiver to work?

The receiver delivers a standard line-level output, so your mixer, powered speaker or audio interface needs an available 1/4-inch or XLR input to accept the signal.

Can I keep using my existing wired dynamic microphones alongside this wireless system?

Yes, the wireless receiver occupies only one input channel, leaving other channels free for any wired microphones you already own.
